Yes! Press Alt+Ctrl+WindowsKey at boot time and the bios will appear on your screen.
hehehhe
No seriously, hold down both mouse buttons when booting up. How ever there isn't much to change in there. It isn't like the PC Bios. You see the Amiga got it right the first time. There isn't any need to un-phuk the setup of Amiga harware like you do with PC hardware. The Amiga just works in *most* cases.
